To all whom it may concern: 1

Be it known that I, JOSEPH Oo'rxvn Bronssnxu, a subject of the' King of Great Britain, residing at North Hatley, county of Stanstead, in the Province of Quebec, Canada,

have invented certain new and useful'Improvements in F lush-Tanks; and I do here-- by declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to flushing tanks, and more particu-- larly to a construction and arrangement of the several parts, whereby the siphoning of the tank will be made much more certain than hitherto, and the defective closing'of inlet. valves and outlet flush pipes and consequent waste of water will be prevented.

Broadly speaking, the construction comprises a flush tank box, a feed water inlet to the same, an outlet passageleading from the box, a stand pipe communicating with the outlet, :1 tube inverted over the upper ings, like reference characters designate the same parts;

In the drawin Figure 1 is-a verticalcross section on lme'1l of Fig. 3, looking in the direction of the arrow; Fig. 2 is a vertical cross section on line 2'2 of Fi". 1, looking inthe direction of the arrow; 'Fig. 3 is a horizontal cross section on line 3-3 of Fig. 1, looking in the direction of the arrow, and showing'the float and connected mechanisms in plan, Fig. 4 is avertical cross section on line 44 of Fig. 1, looking in the direction of the arrow, and showing the feed waterinletand'related parts in sec: tional detail; Fig. '5 is a yertical cross sec tion on line 5-5 of Fig.1, lookingin the direction otthe. arrow; F ig. 6 is a section on line 6-6 of Fig. 5, looking in the direc tion of the arrow, and showing a rear elevation of the float and connected parts; Fig. 7 is a cross section on line 7--7 of F1g.

6, looking in the direction of thearrow; and,

box.

A box 1, of the general form shown in the drawings, may be used. In this box is 'mounted the feed valve chamber 2,'through which water flows to the interior'of the box'. At a central pointin the box is secured the stand pipe 3, having a contracted delivery passage or opening 4 communicating.- with the flush pipe 5. The upper end of this ,standpipe is provided with aplurality of guide and supporting fingers 6, upon which Fig. 8 is an end elevation of the flush tank is seated, in inverted position, a sleeve 7,

provided with guide and spacing lugs 8, which, together with the fingers 6, act .to

spaced apart to form therebetween' an annular chamber 9, which forms the siphon.

In order to insure theaction'of the siphon,

-hold the sleeve 7 and'stand pipe 3 slightly a large open-ended box-like shell or float '10 is provided,.which practically fills Tthe'entire interior of the box 1 except such part thereof as is taken up by other operating parts to be later described. This float is suspended from the interiorof the box by means of the links 11, pivoted respectively to the lower edge of the float and the crank arms 12 of a shaft 13, which passes through the upper end of the box 1, and is rovided with a crankhandle 14, by which it may be rocked.

'The links 11 and arms 12 are so'proportioned as to hold the float a little above the bottom of the box. 1, thus allowing the water to enter beneath the lower edge of the same, and, as the water rises in the box, to form a water seal around the edges of the float. Of course, as the air is compressed in the float by the rising of the water, theffloa't will be gradually lifted. As the float rises, it carries, with it the outer arm of a lever .15,

to'which is connected the valve rod 16, which raises the valve 17 and cuts oittheflow of water to the box 1.

4 In order to allow adjustment ofthe'valve" 17 so that the feed of water may be cut off at various points as desired, the upper end of the valve rod 16 is'threaded and passed being engaged by a nut 19, which abuts against the upper edge ofthe sleeve, the

sleeve being pivotally connectedto the lever through the sleeve 18, thethreaded portion" 11o In order to fill the'usual form of trap to Y which the ipe leads, a bent filling tube 21 is provide which communicates both with the feed water inlet and with the upper end of the stand pipe 3. Communication between the fillin tube 21 and the feed water inlet is establis ed by means of the elbow pipe 22. The pipe 22 is. of considerably reater diameter than the pipe 21, which is nserted in the lower end thereof. Due to this difference indiameter, there is, of course,

an annular passage between the two pipes, through which water flows to the interior of the box 1.

In order to make a perfectly tight joint between the elbow ipe 22 and valve cham her 2, the chamber is bored at its top to receivea tubular boredboss 23, on the elbow pipe, a acking ring 24 of rubberor similar ,materia serving to make the jointwaterproof, and screws or. similar devices serving to clasp the two parts tightly together.

'The size and construction. of the openended shell or float 10 has two particular advantages overall other known constructions for the same purpose. First, because of its size, it acts upon a much greater surface of water for siphoning, and consequently makes siphoning more certain and complete. Second, its unusual size gives it much greater power for-operating the feed water valve, and consequently there is no likelihood of the water filling up clear over the float without operating the valve. Also by constructing. the float as an open-ende' shell of pro .ortionately large size, it is possible to-inc ose the stand pipe and siphon tube within it, and so reduce the size of the flush tank box.

.The siphoning action of the water through the passage between the stand pipe 3 and sleeve 7 is started by depressing the float 10 and thus forcing the water under the lower edge of the sleeve and up through the passage between the sleeve and the stand pipe. The depression of the float is done by swinging the crank handle 14 toward the dotted line position shown in Fig. 8.

In order to allow the examination of, the

operating mechanisms, the box 1 is provided with a rim top or cover 25, having a screened opening 26 for the free passage of air to the interior of the box.

It is thought that the operation and use of the invention Wlll be clear from the preceding.

'Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:'---

1. In a flushing apparatus of the character described, atank, a feed water inlet through which water may be delivered to the tank, a siphon in said tank, a valve for controlling the feed of water to the tank, a float mounted within said tank and inclosing the aforesaid siphon, and connections between said float and the aforesaid valve.

2. In a flushing apparatus of the character described, a tank, a feed water inlet through which water may be delivered to the tank, a siphon in said tank, a float sus pended within said tank and inclosing the aforesaid siphon, and means for depressing saidfloat to start the operation of the .siphon. p

3. In a flushing apparatus of the character described, a tank, a feed water inlet through which water may be delivered to the tank, a siphon in said tank, and an open-ended shell float mounted in said tank and adapted to incl'ose said siphon.

4. In a flushing apparatus of the character described, a tank, a feed water inlet through which water may be delivered. to the tank, a siphon in said tank, a valve for controllingthe feed of water to the tank, a. float mounted within said tank and inclosing the aforesaid siphon, connections between said float and the aforesaid valve, and means for suspending said float above the bottom of the tank.

5. In a flushing ap aratus of the character described, a tan a feed water inlet through which water may be delivered to the tank, a siphon in said tank, a float suspended within said tank and inclosing the aforesaid siphon, means for de ressmg said floatv to start the operation- 0 the siphon,

and means for suspending said floatabove the bottom of the tank.

In witness whereof I have hereunto set my hand inthe presence of two witnesses.
